## Definition of Kilometer

Kilometer is aunit of the metric system mainly used to express a distance. The abbreviation ofkilometer is km. It isa unit of the International System of Units (SI units). Examples: Some examples of distances in kilometers are, the distance from one city to another city, the distance of a runway, the distance you wouldcover while taking a walk can also bemeasured using km.

## Kilometers and Miles

As per the kilometer definition, kmis used to express the distance as an SI unit. A mile is aunit followed in the United States for measuring distance. The metric unitfollowed in the United States is called the "United States Customary Units (USCS)".Even though kilometers and miles are used for measuring the same unit (distance), the value differs.Although kilometer is not a unit of the American metric system (USCS), it is frequentlyused in the fieldof science, medicine, and military forces.

## Distance Conversions

Conversion is needed wherever long distances aremeasured. In this section, we will learn the relation between kilometers and other units of distance like, meters, centimeters, millimeters, miles and feet. We will also learn how to convert other units to kilometers too.

### Kilometer to Meters

Meter is a SI unit of distance. It is abbreviated as m. The relation between kilometer andmeters is given as, 1 kilometer (km) = 1,000 meters (m).

### Kilometer to Centimeters

As meter can be expressed in centimeters as, 1 meter (m) = 100 centimeters(cm). Thus, the relation between kilometer and centimeters is given as, 1 kilometer (km) = 1000 × 100 = 1,00,000 centimeters (cm).

### Kilometer to Millimeters

As centimeters can be expressed in millimeters as, 1 centimeter (m) = 10millimeters(mm). Thus, the relation between kilometer and millimeters is given as, 1 kilometer (km) = 1,00,000 × 10 = 1,000,000 millimeters (mm). Similarly, it is possible to convert kilometer to USCS units, miles and feet.

### Kilometer to Miles

Miles is the USCS unit mainly used to indicate distance. It is abbreviated as "mi". The relation between kilometer and miles is given as, 1 km = 0.62137 mi.

### Kilometer to Feet

Feet is also the USCS mainly unit to indicate length. The singular unit for feet is given as foot. It is abbreviated as "ft". The relation between kilometer and feet is, 1 km = 3,280.84 ft.
